Across
- 7. wave-like series of muscular contractions and relaxations of the circular and longitudinal muscles that surrounds the various parts of the digestive tract
- 10. the process where muscle fibers generate tension and shorten in response to a nervous system signal
- 11. the continuous movement of blood throughout the body, driven by the heart, to deliver oxygen and nutrients to tissues while removing waste products
- 13. twitch muscular contraction that lasts a fraction of a second
- 14. filament model an explanation for muscle contraction based on the movement of the actin filaments in relation to myosin filaments
- 15. protein in muscle tissue that stores and transports oxygen
Down
- 1. a muscle layer that separates the region of the lungs from the region of the stomach and liver
- 2. exercise-induced increase in muscle mass due to an increase in the size,not number of individual skeletal muscle fibers
- 3. a protein found in heart muscles cells that helps them contract
- 4. muscle nonstriated, involuntary muscle tissue found in the walls of internal organs
- 5. the release of tension in muscle fibers, allowing them to return to a low-tension, resting state after contraction
- 6. muscle striated, involuntary muscle found only in the heart
- 8. muscle striated, voluntary muscle tissue that comprises skeletal muscles: also called striated muscle
- 9. adenosine triphosphate
- 12. fibrous connective tissue that connects skeletal muscle to bone
